Abstract(in English) | In this paper, we propose an adaptive algorithm based on accumulated signal processing, which could be applicable to Post-FFT type OFDM adaptive array antenna. Proposed scheme calculates the weight of each element at a particular instantt , by considering both post and pre-received symbols. Since this technique uses additional future information on channel behavior in the weight calculating scheme comparing to the conventional MMSE adaptive algorithms, one can expect performance improvement with the application of the proposed algorithm in fast fading conditions. This paper also discusses the application of proposed adaptive algorithm to OFDM adaptive array. When applying to OFDM adaptive array, first, we allocate few subchannels to transmit pilot symbols. At the receiver, we perform the proposed adaptive algorithm to those pilot subchannels, and interpolate the weights for the data symbols which are allocated between the pilot subchannels. This paper also contains simulation results to confirm the system performance improvement with the application of the proposed algorithm. |
